Use the right question for each small item
An accessory shortlist can contain eyewear, belts, headwear and small goods, each with different comparison fields. Group like items first. For eyewear, keep lens width, bridge width and temple length as three separate measurements; for a belt, ask which points the stated length runs between.
Then check the selected quantity and included parts. Several colors in one picture may be choices rather than a pack. Record dimensions for small goods and the size information supplied for hats or socks. Appearance is useful for comparing a design, while material or protective-performance claims need their own evidence.
